Northern lights in New York State tonight
New York, USA · 49° magnetic latitude · Kp 5 threshold
Kp 6 is at the threshold for New York State. Aurora may be visible from a dark site if cloud cover permits.
7-day outlook for New York State
Tonight shows the live Kp reading. The nights after it show the Kp expected from any coronal mass ejection DONKI predicts will arrive that day, and a quiet baseline of Kp 2 where no arrival is forecast.
Based on CME arrival predictions from NASA DONKI. Arrival times ±6 hours.

What Kp is needed here?
New York State sits at a magnetic latitude of approximately 49°N. The Kp index - a global measure of geomagnetic activity on a scale from 0 (quiet) to 9 (extreme storm), updated every 3 hours - needs to reach Kp 5 before the auroral oval expands far enough south to be visible from here.
At Kp 5, visibility is possible from New York State but skies need to be clear and dark. Cloud cover and light pollution remain the main obstacles even when Kp is high enough.
Best dark sky sites near New York State
Light pollution is the biggest obstacle after cloud cover. These sites give you the best dark northern horizon within reach.
Adirondack Park - Long Lake / Blue Mountain Lake
Get directions ↗The Adirondacks contain the largest designated wilderness area east of the Mississippi. Long Lake and Blue Mountain Lake sit at the park's interior, roughly at 44°N geographic latitude with Bortle 2-3 conditions. The north-facing shores of Long Lake give open sky toward the Canadian border with no light domes to the north. Blue Mountain (1143 m) is accessible by trail and gives elevated sky access. About 3.5 hours from New York City via I-87. Autumn (September-October) before the hunting season is the most popular aurora season. The lack of western development keeps the northwest Adirondacks genuinely dark.
Tug Hill Plateau
Get directions ↗A forested upland plateau west of the Adirondacks between Watertown and Utica. At 500-600 m elevation with minimal population, the plateau gives dark skies in all directions. Whetstone Gulf State Park on the plateau's south edge and the state forest roads in the interior give dark-sky access. The north-facing positions look toward Lake Ontario and Lake Erie with no significant light pollution beyond. Bortle 3. Positioned slightly farther north than the Adirondacks' southern approaches. About 5 hours from NYC, more easily reached from Buffalo or Rochester.
Allegany State Park
Get directions ↗New York's largest state park, in the southwestern corner near the Pennsylvania border. The forested hills and valleys give Bortle 3-4 conditions with a clear northern sky. At 42°N geographic latitude it is the southernmost option but benefits from distance from Buffalo's light dome. The Red House and Quaker areas of the park give roadside sky access. Accessible from Buffalo in about 1.5 hours. A practical option for western New York residents wanting a dark sky without a long drive.
Cherry Springs State Park (Pennsylvania, 3.5 hr from NYC)
Get directions ↗Just across the New York-Pennsylvania border, Cherry Springs is one of the designated International Dark Sky Parks in the northeastern USA. At 675 m elevation with Bortle 1 conditions from the main observation field, it outperforms any New York State site for darkness. It is 215 miles from Philadelphia and around 260 miles from New York City via I-78 and US-15. For New York City-based aurora chasers, Cherry Springs is the closest Bortle 1 dark sky in the region.
Best time to see the northern lights in New York State
At 49°N magnetic latitude, New York State sits at the lower end of regular aurora territory. Only the deep mid-winter months of November through January offer nights dark enough for aurora to be visible, and only then when a significant geomagnetic storm pushes the auroral oval this far south.
Activity peaks around the September and March equinoxes, when Earth's magnetic field geometry is most favourable for coupling with the solar wind. Events during these two windows tend to produce the strongest displays of the year for observers at New York State's latitude.
Outside November through January, twilight is too bright for aurora viewing even during significant storms. The season is short, but the equinox months on either side of winter can extend it slightly when storm timing aligns.
How often does the aurora appear in New York State?
Average nights per month the Kp reached New York State's threshold of 5+, from 15 years of geomagnetic data (2010–2024).
Counts the Kp 5+ threshold only - cloud cover and local darkness are not included.
